Left dot of the rear night sight dead out of the box. I had to send the slide back to SIG. Other than this, no complaint about the experience of shopping and shooting. I put 100 rounds through it without any issue.

My only issue with this pistol out of the box is that the larger backstrap seems to have a slight void, causing a click when held tight. First 100 rounds with no issues. Grabagun was great, pistol was in my Ffl's hands within 6 days of placing my order. I will deninitely use them again.
